This paper discusses the use of Python for developing
audio signal processing applications. Overviews
of Python language, NumPy, SciPy and Matplotlib
are given, which together form a powerful platform
for scientific computing. We then show how SciPy
was used to create two audio programming libraries,
and describe ways that Python can be integrated
with the SndObj library and Pure Data, two existing
environments for music composition and signal
processing.
